I usually stick with JK treated or untreated. What's the difference with between the JK Wonder and Thunder Rubber? How do they compare to the treated and untreated tires?

A motor is only as fast as the chassis it's in.

I have not put a durometer to the tires, but from first hand experience the Alpha Medium Wonder Rubber (Thunder Rubber) is a tab bit harder then the JK Wonder Rubber tires. I could not get my car loose enough with the JK tires, but when I put the Wonder Rubber tires on from Alpha I could get the rear end to slide rather then dig in.

Alpha also has the hard Wonder Rubber, but I've never had to try that.

Just my opinion of course.

Thunder Rubber is the same as Alpha's medium Wonder Rubber and both are a bit softer than the JK Wonder Rubber Rubber.

Man, you guys are disappointing me I tough I was on a x-rated site sorry. :laugh2: So what rubber makes it slide more?
I like untreated my self but then it depends on the temperature of the track?
Kelly and Alpha tires is my gig because that's the way I roll.

Just leave them on the car for six months without racing - they slide real good. :laugh2:
